I was a bit disappointed there's no yellow option to replace my original Instinct Solar, so I did a 5-minute custom job on my graphite Instinct 2 Solar by using the old strap and colouring in the lettering on the bezel to match. I used a crayon for this rather than acrylic so it's easy to revert to black or change to another colour if I decide to. I think it'll still be pretty resilient based on previous experience, and if it does start to wear away, it's a quick job to redo it.
If anyone else is planning on personalising their new Instinct 2s, then please post below - ideally with photos!
